Fueled by anger over her husband's affair, Clara Harris was trying to smash his lover's luxury sport-utility vehicle when she inadvertently ran over him, she testified Friday.

Clara Harris, a dentist who first took the stand Wednesday in her murder trial, was emotional but composed as she recounted the evening of July 24, when she and her stepdaughter caught orthodontist David Harris and lover Gail Bridges at a suburban hotel where they had met for a tryst.

"I was in so much pain, it was a physical pain that I was feeling. I wasn't thinking anything," Harris said, describing how she returned to her car after brawling with Bridges inside the Nassau Bay Hilton lobby.

"Suddenly, I thought about smashing my car against her car and then I (picked) up speed."

Clara Harris saw three figures near Bridges' black Lincoln Navigator. Two dodged right, she said, but her husband moved left, toward her approaching Mercedes.

"I saw some surprised eyes," Clara Harris said.

She veered around the Navigator toward a grassy median within the hotel parking lot when, she says, things got fuzzy.

"I think I closed my eyes. After that, I didn't know who was driving," Clara Harris said, often using hand motions to punctuate her words. "Everything seemed like a dream."

Clara Harris said she snapped out of it when her stepdaughter, 16-year-old Lindsey Harris, was screaming for her to stop. That's when she got out and saw her husband lying on the pavement.

"I saw David and I couldn't understand what he was doing there," she said. "I had just seen him running and I didn't know how he got there.

"I said, `David, David, please talk to me."'

Blood streamed from his ears and his mouth and eyes were slightly open, she said.

"I checked his heartbeat and pulse. Both were good, but fast," she said. She then called for an ambulance.

"Everything was in slow motion. I don't know if my voice came out," she said.

Clara Harris gave her statement to police around 5 a.m. because she "just wanted to talk to somebody." Then, as now, she said the fatal collision was an accident.

Prosecutors contend she intentionally ran down her philandering husband, who had been dating a receptionist at his Johnson Space Center-area practice since May 2002.

On cross-examination, Assistant Harris County District Attorney Mia Magness repeatedly fired the line "You got what you wanted, didn't you?" at Clara Harris, who did not appear to wither under the pressure.

Magness attempted to dispell any sympathy defense attorney George Parnham might have built earlier in the day by noting the couple's practices pulled in between $50,000 to $60,000 monthly, with David Harris earning the lion's share.

Magness insinuated a divorce could damage the lucrative family business.

"There would not be any more dream of the two of us," Clara Harris said. "There would be another dream I presume."

Clara Harris consistently testified she wasn't angry --only hurt -- about the infidelity until Magness got her to acknowledge her emotions hardened when she saw Bridges' Navigator, which she vandalized before attacking her in the lobby on July 24.

Leading up to her dramatic description of the collision, Clara Harris said she had worked tirelessly for a week since learning of the affair.

On July 18, the day after he confessed to sleeping with Bridges, David Harris and his wife spent an evening at a Houston airport bar going over the attributes and liabilities of each woman in exacting detail.

Clara Harris took notes on bar napkins, which were introduced into evidence. While Clara Harris might have had a slight edge in appearance and intelligence, he said his adulterous lover was a better listener.

The napkins revealed Friday that David Harris thought his wife was overweight, "dominated conversations without letting anyone else talk" and was a workaholic, all in contrast to Bridges, whom he described as "petite with the perfect fit to sleep with, holding her all night."
